The 25-minute long story will feature an introduction from the award winning writer himself, Sir Michael Morpurgo (War Horse), and will be narrated through classical music in an original score written by Oscar award-winning composer, Rachel Portman (The Little Prince).

It will be performed by the BBC Philharmonic featuring singers from the Hallé’s family of choirs and will be recorded at Media City UK, Salford.

Based on original illustrations by Emily Gravett and adapted for the screen by novelist, poet, and playwright, Owen Sheers, Mimi and the Mountain Dragon is a story about a village that quakes in fear of the mighty Mountain Dragon.

One winter, a shy little girl called Mimi finds a tiny baby dragon asleep in her family woodshed. Mimi takes the perilous journey through blizzard and darkness to return the baby dragon to her mother who all the villagers fear.

Charlotte Moore, Director BBC Content, said: “We’re delighted to be bringing this enchanting mix of music and storytelling to BBC One this Christmas. Sir Michael Morpurgo’s wonderful book will be perfectly complemented by the music of Rachel Portman, The BBC Philharmonic and singers from the Hallé’s family of choirs - a real festive treat for all the family.”

Sir Michael Morpurgo commented: “Many years ago, in the Engadine Valley in Switzerland, I saw village children in red hats, cracking whips, ringing cowbells, banging drums, creating a great cacophony of noise, as they paraded up through the village. I asked why this was happening. They are driving away wicked spirits, I was told. So began my story of Mimi And The Mountain Dragon.

"And now, extraordinarily, wonderfully, this little story is being made into an animated film, by Leopard Pictures and Factory Create.

"And what a team BBC Music have put together. There is music by Oscar-winning composer Rachel Portman, a script by Owen Sheers, the great Welsh poet (so he knows a thing or two about dragons!) and with magical drawings from the supremely talented Emily Gravett. I can’t wait to see it!”

Jan Younghusband, Head of BBC Music Commissioning for Television, added: “At the BBC we have a proud heritage of finding new ways to introduce children to classical music, stretching right back to Benjamin Britten’s Young Person’s Guide To The Orchestra, The BBC’s Ten Pieces project and now Mimi And The Mountain Dragon.

"It is an honour to work with Sir Michael Morpurgo, Rachel Portman, Owen Sheers, Emily Gravett, Leopard, Factory, The BBC Philharmonic and Hallé’s family of choirs to bring classical music to audiences everywhere with this film.”
